Controlling electric field distribution in high voltage components is critical to avoid excessive electric stress on the insulation and thus reducing the risk of insulation breakdown and damage to equipment. For subsea applications this is even more important due to the costs involved in accessing and replacing the damaged parts. This paper describes how COMSOL Multiphysics has been used for modeling electric fields in critical components using electrostatic 2D simulations in the AC/DC module.
